Understanding TUN 618

TON 618 is an extremely active black hole with a luminosity 140 trillion times that of the sun. Its massive energy output is due to its accretion disk, composed of hot gas and dust. The disk is about 4.7 times the size of our solar system, containing a vast amount of matter being pulled into the black hole. As TON 618 feeds on this mass, it grows larger over time, significantly increasing in size over the past 10 billion years.

What is the estimated luminosity of TUN 618 compared to our sun?

• 140 quadrillion times

• 140 trillion times

• 140 billion times

• 140 million times

What is the primary reason for TUN 618's massive energy output?

• Its age

• Its accretion disk

• Its size

• Its distance from Earth

How large is the accretion disk around TUN 618 compared to our solar system?

• 1.7 times

• 2.7 times

• 3.7 times

• 4.7 times

What does the size of the accretion disk indicate about the matter being pulled into TUN 618?

• It contains no matter

• It contains a large amount of matter

• It contains a moderate amount of matter

• It contains a small amount of matter

Why is TUN 618 larger today than it was 10 billion years ago?

• It has been feeding on mass

• It has been losing mass

• It has stopped consuming mass

• It has remained the same size
